ContextVault captures every chat across ChatGPT, Claude, Gemini, and more — stores them locally, and exports as Markdown or ZIP.
Every chat contains insights, code, or ideas you might need again. But today, that knowledge is scattered, locked, or lost.
Every time you switch between ChatGPT, Claude, or Gemini, your working context resets. You start from zero.
Long conversations get truncated. The most important insights vanish before you can save them.
Your conversations are scattered across accounts, providers, and sessions. No single source of truth.
ContextVault sits quietly in your browser, capturing AI conversations as they happen — so you never lose context again.
DOM + Network hybrid engine records every message as it streams — across all major LLM platforms.
IndexedDB stores everything in your browser. No cloud, no sync, no third party ever touches your data.
